Which cells are pigment-producing cells in the epidermis?

• A. Melanocytes
• B. Langerhans
• C. Keratinocytes
• D. Fibroblasts

Answer: (A)

Pigment production in the epidermis is carried out by melanocytes. These cells reside in the basal layer of the epidermis and synthesize melanin, which is packed into melanosomes and transferred to nearby keratinocytes. This melanin distributes to give skin its color and helps shield skin cells from UV damage. Langerhans cells are immune cells in the epidermis that function in antigen presentation, not pigment production. Keratinocytes are the main epidermal cells that make keratin to form the protective barrier, not pigment. Fibroblasts are in the dermis and produce connective tissue components like collagen, not pigment.
